I've got my t-shirts and have printed out my disigns and I'm almost ready to start making my disney shirts. I have two questions before I begin and hope that someone can help. 1. I've seen that parchment paper is recommended to use over the disign. Does anybody use anything else that works as well? 2. How long to you apply the heat with the iron? Do you move the iron around on the image or just apply direct heat? Thanks in advance from a newbie.
